It looks like you are looking for a wiper blade (or possibly a maintenance part) for a Samsung ML1610, ML108, ML109, ML106, ML1043, or ML4521 printer. However, it's important to clarify that the models listed are part of Samsung's laser printer series, and typically these printers don't use "wiper blades" in the sense that cars do.

In the context of laser printers, wiper blades are part of the drum cleaning assembly. They help to clean the drum after printing. These components are critical in preventing print quality issues like streaks or smudges.

For the models you mentioned, here are the correct types of maintenance parts:

1. Samsung ML1610, 108, 109, 106, 1043, and 4521 Printers: These printers primarily use toner cartridges, fusers, and drum units. In certain cases, the drum cleaning blade (wiper blade) is part of the drum unit, but this can vary depending on the specific model.

If you're experiencing print quality issues and believe the wiper blade (drum cleaner) needs replacement, you might need to replace the drum unit or specific toner cartridge parts. You can find drum units, toner cartridges, and other printer parts on sites like Amazon, eBay, or directly from Samsung or third-party printer part suppliers.

Would you like more detailed help finding these parts? If so, please confirm the specific issue you're facing or the exact part you're looking for.
